Outdoor Power Equipment and Small Engines - 8hp tecumseh runs wide open

I have a 1984 ariens srm830 with a 8hp tecumseh engine.I rebuilt the carb on it and hooked the linage back the same as it was before and i mowed with it twice and everything worked just fine.I was mowing and hit a rock the size of a baseball and about 2-3 min later it started running wide open.When i hold the govener linkage back it runs fine and when i let off it runs wide open.I figured i damaged the gov inside so i took it apart and the plastic spool looking thing was all chewed up so i replaced it and it still wants to run wide open!I keep thinking the linkage is hooked up wrong but why did it run fine before and now it runs wide open?Can anyone please tell me whats wrong and were i could get a diagram of linkage hook-up for the carb and the choke and a exploded view of the engine? THANK YOU in advance..Rick

you are supposed to set governor lever to throttle wide open. governor pulls throttle rod back to closed position. top rod connects governor to throttle. bottom sring to carb linkage. long end of throttle rod goes to governor lever. adjust to get it idle down. governor lever towars head is wide open and towards seat is closing. your supposed to set governor with everything else disconnect. but if in a hurry unloosen lever and adjust to about 3/4 speed with linkage in fast position. sounds like you did not put throttle rod in right and its sticking throttle plate in wide open position. redo throttle rod to make sure its right so throttle plate can move. short end of rod goes down on hole in throttle plate and long end hooks on governor. it should move freely.

Hello Rick!

Sounds like you need to adjust the governor arm. Set the throttle to wide open, loosen the governor lever, rotate the governor shaft as far as it will go in the direction that it would go if it were revving the engine, hold it there while you tighten the lever screw. This should get you back in shape.

I checked linkage and it is and was connected like you said,so thats all straightend out.I tryed moving the govenor rod around and it seems to be bringing it out of its fits so once i get everything readjusted it should be back to normal.....Thanks alot guys you have been a great help!!!

Great! Glad we could help!
